This earbuds has been amazing, definitely good quality product. For this price, it's totally worth it. I have bought other brand's earbuds around the same price point however it kept going out of sync. I don't have the issue with this one. I'm so impressed with the active noise cancelling, it's so good that I really need to be careful/turn ANC off when I'm crossing the road checking for cars. It fits well into the ears and did not fall off when I'm out for a run. Long lasting battery after only one full charge. I only charge it once after every 5 days or so using it.
